The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.
Advanced simulation, new toolpath techniques aid programming of highly complex machinery. CAD/CAM software developers continue to refine simulation capabilities and toolpath techniques that enable programming highly complex equipment including multiaxis and multitasking machine tools.
The simple proposition that no two automation solutions using robotics are alike because no two manufacturing processes are identical presented a major challenge to Daniel Drennen of Deshazo LLC (Alabaster, AL).
Entrepreneurs and existing manufacturers are making 3D printers that automate production of composite parts, and are unique in their design.
Lightweighting is so established it’s now part of marketing for new vehicles. Automakers routinely detail how much less models weigh than their predecessors. General Motors Co., for example, has said a range of its vehicles is anywhere from almost 250 lb (112.5 kg) to 700 lb (315 kg) lighter.
Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.
There’s an old saw that if bumblebees were aeronautical engineers they would know they can’t fly. Quite apart from the miracle of their flight, bees also happen to make a lightweight structure of surprising strength, just the sort of thing you’d want if you were building aircraft: honeycomb.
When GE decided that additive manufacturing was the way to go for making metal fuel nozzles for its new LEAP engine, the company touched off interest in other shops to move 3D printers from the design studio to the factory floor. It also stepped up the focus on safety standards for metal AM.
The first kilowatt-class fiber laser for material processing was introduced by IPG Photonics in early 2002. Since that time, the adoption of fiber lasers for production applications has grown at a rapid rate. Today, fiber lasers are becoming the choice for most major production laser applications as well as converting traditional welding and cutting processes to fiber laser technologies.
New coatings are going the boutique route, using multiple layers and new materials to optimize for a particular application
